This Troubleshooting is for Connecting a Bluetooth device DIRECTLY to your Windows Computer's Built-in Bluetooth.
The Built-in Bluetooth of some old PCs might not work, or not work well, thus, you may not be able to use the direct Bluetooth connection, or have unstable connection, hear choppy sound cutting out intermittently, etc., in this case, please try the following solutions: 

Solution 1.  Reboot your Bluetooth Driver
  1) Right-click the Start button, select Device Manager.
  2) Find “Bluetooth” section,  then Right-click on your device Bluetooth driver and select  “Disable device”.
  3) Restart your PC and repeat the above steps to Enable the Bluetooth driver again   (select  “Enable device”)
  4) Pair your Bluetooth Headphone/Speaker/Receiver with the PC again.


Solution 2. Use an External Bluetooth Driver
This method essentially "Bypasses" your Windows' built-in Bluetooth. Please see our Avantree DG10, DG40S , DG45 or Avantree DG80 for more details or contact us at support@avantree.com.

Check Point 1: Have you Connected/Paired it Properly?
Check on your device Bluetooth device list, it should say "Connected" on the menu. If not, please try to pair it to your device again.

Check Point 2: Have you been Switching between APPs?
Sometimes when you're listening to music and a call comes in, the Headphones/Speaker can have issues switching back-n-forth... this is a common Bluetooth issue and happens to every Bluetooth Headphone/Speaker. 
Please choose the headphone/speaker again (if applicable) or reboot the headphone/speaker and pair them up again.

Check Point 3: Have you Charged the Headphone/Speaker?
This might seem like a simple solution but when the device is low on battery, a wide variety of issues may occur. Please make sure that it has sufficient battery level.

If you've checked everything above but still no sound, please try the methods below.

Method 1: Try it on a Different Device.
If you have another phone, another laptop etc... try to connect the Headphone/Speaker to it and see if it works on the other device. 
If yes, it's probably something to do with the settings on your original device, please try again.
If no, please contact us for support, you may have a faulty unit.

Method 2 (For Laptops/Computers): Check the Audio Settings.
For Windows, go into Sound Settings and Sound Control Panel. For Mac, go into Sound Preferences.
Make sure that the Headphone/Speaker you'd like to use has been selected as the Audio Output/Input device.
If you're using a Meeting Software such as Skype or Zoom, you may need to go into the app itself and adjust the settings in there as well.

Method 3: Factory Reset.
If none of the methods above work, please factory reset the Headphone/Speaker and pair again. Please remember to delete the Avantree device from the paired Bluetooth device list on our sound source device, before attempting to pair again.

If factory reset still can't get it to work or if you have any more questions or need further assistance, feel free to contact us at support@avantree.com

If you are still having difficulty pairing the Avantree Headphone/Speaker/Receiver to your devices, please refer to the methods below to troubleshoot.

Check Point: Did you Get the Headphone/Speaker/Receiver into Pairing Mode?

Powering on does NOT mean pairing mode. Pairing Mode for Avantree = The LED indicator on the Headphone/Speaker/Receiver flashing RED & BLUE. If it's not doing that, it's not in pairing mode, you won't find it on your device.

Other than the indicator, if you're using a Headphone/Speaker that has voice prompt (i.e. it says "welcome to Avantree" when you power it on,) it'll say "Pairing" when it's in pairing mode.

If it's flashing RED & BLUE yet you can't connect it, please refer to the steps below.

Step 1: Reboot it and try again.

Yes, the good o' soft reset often resolves the issue. Please give it a go. Please also try rebooting your Phone/Computer.
If you still can't get them to connect, please proceed to step 2.

Step 2: Try it Somewhere Else.

Bluetooth connection can often be interfered with by other wireless connections such as WiFi Router, TV streaming device, or even another Bluetooth device. Please either move them away or try to do the pairing somewhere else.

If you are still unable to pair, continue to Step 3.

Step 3: Factory Reset.

Factory reset the Avantree Headphones/Speaker/Receiver may help. If you're not sure how to do the reset, please follow the below steps to find the instructions:

1.Go to Avantree.com

2.Enter "Product Name/Model Number+reset" and search. Click "Support " and you will find the guide of how to factory reset your device.

After resetting, the device should automatically reenter pairing mode.

If you have any more questions or need further assistance, feel free to contact us at support@avantree.com

Yes, you can use the microphone on your wired headphone.

If you find that you can't use the Mic on your wired headphone, please try to turn off the AS70 and turn on again. Then the mic on the wired headphone will work.

Many Avantree products have incorporated the latest "aptx low latency" codec technology, for superior stereo quality sound without any noticeable delay (known as latency).

• What is aptX Low Latency - https://www.aptx.com/aptx-low-latency
• Certified aptX Low Latency device list - https://www.aptx.com/products?field_aptx_type_tid=484

* Important note*

To take advantage of the better performance of aptX Low Latency codec, the other side Bluetooth device must support the same codec. If the other side device only supports the normal aptX codec, or the SBC one, these codecs will be used instead.       

How about the audio delay when use different wireless audio codec?

Note: The latency for FastStream is almost the same as aptX Low Latency, but the audio quality of aptX Low Latency is better.

Here are a few things you'd want to know about Bluetooth...

1. Bluetooth by nature is a short-range wireless technology.

Bluetooth was initially made specifically for wireless headsets hence its “range” was never meant to be anything more than the length of a typical backyard.

2. Bluetooth Signals are easily interfered with.

Much like almost any other modern wireless technology, Bluetooth signals can be negatively affected by things like walls, floors, other wireless devices, or even a human body.

If you want a better range & less interference, try to stay clear of the things mentioned above.

3. There are two types of Bluetooth.

In short, they are “Class 1” and “Class 2.”  Class 1 has better range (100m/300ft) but drains your battery faster, whereas Class 2 has a shorter range (10m/30ft) but is more efficient when it comes to battery usage.  

4. The “Actual Range” depends on a lot of things.

Things that can affect the range: Bluetooth version, Bluetooth type, Bluetooth profile, Brand & make, where you’re using it, what’s around you… etc and many more. Getting a bad range doesn’t necessarily mean your device is bad; try it elsewhere before you give it a conclusion.

5. The “Transmitter” and the “Receiver.”

Every Bluetooth connection consists of a “transmitter” and a “receiver.” The “transmitter” sends the signals to the “receiver.” In a typical Bluetooth headphone connection, your phone is the transmitter and the headphone is the receiver.

There are cases where one device can do both, but it is unlikely that they’ll be able to do both at the same time.

Here are some examples:

• Transmitters: Phone, Computer (can sometimes use as receiver), TV.
• Receiver: Headphones, Speaker

As you may know, earbuds get dirty pretty easily... Earwax, dust, water etc. can all do damage to them. Uncleaned earbuds may lead to...

• Music sounding muddy or muffled
• Different volume on the two earbuds
• Abnormaly low volume / tinny sound after using for a period of time

Daily maintaince can effectively eliminate such problems.

• Before wearing the earbuds, make sure to clean the inner side of the ear.
• Always wear and use earbuds in dry condition.
• After using the earbuds, wipe the inside of the earbud tip with a soft and dry towel to remove dust, earwax, or oil from your skin.

If you're already experiencing different volume levels between the two earbuds, please try to follow the following steps to clean them out:

(These apply to all Avantree earbuds, but the following uses the NB18 as an example.)

1. Materials you'll need: a cotton swab and dried brush (if you can't find the black cleaning brush, a toothbrush can work instead.)

2. Take off the earbud tips from the earbuds smoothly. Do not detach the earbud tip from the earbud excessively as it may tear.

3. Use a cotton swab and dried brush to remove any debris and foreign materials.

4. If foreign substance is still present, try brushing the earbuds again to dislodge the remainder.

5. After you finish cleaning, please assemble the earbud tip back to the earbud properly. Cover the latch at the bottom of the earbud with the earbud tip like below.

Please note: Do not use liquid like alcohol or soapy water for cleaning earbuds as some of our earbuds are not alcohol-proof or soapy-waterproof.

If the problem still exists after cleaning the earbuds, please contact support@avantree.com for help.
